Section 4.2. says:

   The first octet of the packet header is called the "Packet Tag".  It
   determines the format of the header and denotes the packet contents.
   The remainder of the packet header is the length of the packet.
   ...
              +---------------+
         PTag |7 6 5 4 3 2 1 0|
              +---------------+
         Bit 7 -- Always one
         Bit 6 -- New packet format if set

It should say:

   The first octet of the packet header encodes the packet format and
   the "Packet Tag".  It determines the format of the header and denotes
   the packet contents. The remainder of the packet header is the length
   of the packet body.
   ...
              +---------------+
              |7 6 5 4 3 2 1 0|
              +---------------+
         Bit 7 -- Always one
         Bit 6 -- New packet format if set

Notes:

Only a part of the first octet (depending on the packet format, i.e.
depending on bit 6 of the first octet) is the Packet Tag.
The packet consists of header and body. The encoded length is the length
of the packet body.
--VERIFIER NOTES--
The suggestion is incorrect. The first octet of the header is called the packet tag. The packet tag contains other information besides tag information, but it is nonetheless called (and has always been called) the packet tag.
